a The present invention relates to improvements in aeroplanes and having for an object an aeroplane providing a novel arrangement of extension planes or wings, whereby to lend to the flight and lifting efficiency of the machine in order that the same 'may be successfully used where the body or fuselage of the aeroplane is much larger than those now in common use.

Another very important object of the invention resides in the provision of control means incorporated in thelifting planes or swings to afford greater efliciency in launching the aeroplane in the air and in landing on the ground.

Another very important object of the invention resides in the provision of an aeroplane of this nature wherein a plurality of retaining surfaces which are distributed along the fuselage at various points for the purpose of augmenting the lifting and retaining efliciency thereof.

7 Another very important object of the invention resides in the provision of an aeroplane of this nature which is easy to control in the necessary maneuvers incident tosuccessful flights of a relatively large aeroplane in the air.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as .willbe hereinafter more fully described and claimed.

.Referring to the drawings detail it will be seen-that the numeral 5; denotes an -elon gated fuselage having in its noseor front end a. motor, 'interiorly thereof and not visible inithe drawings; with a propeller '6 operative- 1y connected therewith in the usual well I knownimanner. i is r The tailstruoture is conventional and includes rudders 7 and elevators 8.

Adjacentfthe erally extending wings 11=of the -m0noplane type whichare providediin their trailing edges-with the usual ailerons'12, and also with sustaining plane members 14:. a At aboutthe center ofthe fuselage are laterally extending wing structures 'of the biplane type including upper wings 15 and lower wings 16 connected'togetherby-their rods 17 and it is to front provide a pair of latbe-notedthatthe-bottom wings -16,do notproject outv as far as the upper wings 15.

Motors 18 are supported onthe lower wings 16 and have jforwardly disposed propellers operatively connected therewith. .In the trailing edges of theupper wings 15 are the usual aileronsQO-and my improved sustaining plane members l laand in the trailing edges ofthe lower wings are similar members 14a. r

At the .rear of the fuselage infrontof the tail structure there isprovided biplane wing structurescomprising upper wings 15.; and lower *w1ngs .16 simllar in] all respectsto wings 15 and 16 respectively and motors 18" aremounted'onthe wings lorand havefront prope1lersl19. v y c The wing151is provided withailerons: 20 andwing 16.is providedwith members'llA.

"Referring to Figures A and 5 particularly it will be seen that I have illustrated in detail the mounting of the members 14 and 14a all of which are similar that is hingedly mounted as at 22 at their forward edges and 5 at the trailing edges of the respective wings. The members 14a which are disposed one above the other in the wings 15 and 16 or 15 and 16 are connected together by links 23 pivotally engaged as at 24 with the entering 10 edges of the members. The upper members 14 and 14a are provided with bars 25 rising therefrom and the lower members 14a arerprovided with bars 26 dependingtherefrom.

In the fuselage there is a lever 28. A cable i 1 29- is engaged with the leverQS and has I branches trained over pulleys 30 and connect ed tomembers 26 while to the lever 28 there. v

is also engaged a cable 31 having branches each biplane wing structure being shorter than the upper wings, motors mounted on said lower wings and having forwardly disposed propellers 'operatively connected thereto, all of said wings having recesses in their rear edges located adjacent the fuselage, a sustainmg plane member hingedly connected at its front edge with the front wall of saidvrecess, and means for raising and lowering the traillng edges of said members simultaneously.

In testimony whereof I aflix my signature. EARNESTV BEAVER.

trained over pulleys3 2'and connected with I bars 25.

In the above detailed description it will be 7 seen that I have devisedlan aeroplane with a great amount of sustaining surface afforded by a plurality of planes or wingsand particularly have provided controlscenabling the aeroplanes to take off from the ground in-spite of'its' great length and to make an easy and safe landing. 3 With the aid of the sustainingplane member's, it will be seen'thatthis-aeroplane may be made to talie the air as easily as the aeroplane of the present day design: since these members are hinged so as to be let down so that their trailing edges may catch theforce 35 of-air in the takeoff while the ship is aloft they can be pulled up even with the rest ofthe. wing throughthe medium'of a single control lever to'be complementarytovthe lifting surface of said wings.- 40 It'is thought/that the construction, opera-- tion, utility and advantages of this invention will now be quite apparentto those skilled in I this 'art without a more detailed description thereof." Y The present embodiment of the invention has been disclosed in considerable detailmerely for the purposes ofexemplification since 7 in actual practice'it attains the features of advantage enumerated as desirable in the 60' statement of theabove invention and description." -J s It will be apparentthat changes in the details of construction,-'and in the combination and arrangement of parts mav be resort- 55 ed to without departing from the spirit or .scope ofthe invention as hereinafter claimed or sacrificingany of its advantages, a Havingjthus' described my invention; what I claim as new and desire to secure by Letters 60 Patentis: y V
